Sounds like a problem with your injector or injector sensors. One of the nice things about the EFI`s are the ability to hook up a diagnostic unit to the motor and then a tech at a merc dealership would be able to tell you exactly which sensor or injector is the problem

Dont have the manual in front of me...recollect that there's two types of warnings. The pulsating warning is oil (starts with 30 minutes of oil left) or the fuel filter (or sperator, something like that) may have water in it. Running outboard with cover off, is a little black box that would have a red light lit if that's the case. If oil full & no red light, may be oil injection system...would also check to make sure lines aren't pinched, etc. Mine has been specific to oil the two times its gone off.

The full non-pulsating is engine overheat. Not sure beyond that.

Not much, but hopefully gets you going.

The constant ticking sound may be a bad piston from the last time it got hot. This is not good. Check the compression to test for piston damage. If you have a bad piston, you will find the bad water flow while solving the piston problem. You may have a piece of old impeller stuck in one of the little channels some where.

Water pump


The water pump is a flexible impellor located in the top of the bottom section of the leg of the outboard. It is driven by the drive shaft to the prop that is spinning all the time the motor is running. You will find it behind or near the water inlet slots at the bottom of the leg
